It shows Mr Ashby discussing how to sell a pro-gun message to Australians, who remain overwhelmingly supportive of the strict gun laws implemented by John Howard in the wake of the Port Arthur Massacre in 1996.

In polling published last year, Essential Research found just 7 per cent of Australians thought the country’s gun laws were too strict, compared to 62 per cent who felt they were “about right” and a further quarter who said they were too weak.

“I said if we were fortunate enough to get into government and have the balance of power, we would have the government by the kahunas. I won’t use the word that they’ve said last night, it would be inappropriate of me to do so,” Mr Dickson said.

“But that means very clearly, and I don’t know if most men here understand that, it means you’ve got the balance of power.”

Part two of the documentary shows officials from America’s largest gun lobby, the National Rifle Association (NRA), advising Mr Dickson and Mr Ashby on how to undermine Australia’s National Firearms Agreement.

Their suggested tactics include co-opting journalists to write pro-gun stories and targeting sections of the population with messages “that will get people outraged” about gun control.

“You want to put messaging out there that will get people outraged. That will get them mad. Easy to understand,” an NRA official says.

The footage that already aired earlier this week showed Mr Ashby and Mr Dickson talking about soliciting funding from the American gun lobby and using it to weaken Australia’s laws.

To that end, they set up a meeting with Koch Industries, a company that donates hundreds of millions of dollars to conservative political campaigns in the United States.

“They have more money than God, Jesus and Mohammed all put together. All of them,” someone tells Mr Ashby and Mr Dickson in tonight’s episode.

Ms Hanson has yet to appear publicly to respond to the undercover footage, though she did post an unapologetic tweet yesterday.

“I was shocked and disgusted with the Al Jazeera hit piece. A Qatari government organisation should not be targeting Australian political parties,” Ms Hanson said.

“This has been referred to ASIO. After the full hit piece has been released I’ll make a full statement and take all appropriate action.”

Mr Ashby and Mr Dickson struck a similar tone at their press conference, but also blamed a late-night drinking session for the documentary’s more outrageous moments.

Mr Dickson repeatedly accused the undercover journalist, Rodger Muller, of being a “spy” employed “by a Middle Eastern country” to interfere in Australian politics.

Mr Ashby called the documentary “a deliberate set-up by the Qatari government”.

“He set these meetings up,” he said of Mr Muller.

“This is skulduggery at its worst. This is the very first time Australia has witnessed political interference from a foreign government.”

Adding to One Nation’s woes, the undercover investigation also caught Ms Hanson on a hidden camera appearing to suggest the Port Arthur Massacre, where a gunman shot and killed 35 people, was a government conspiracy.

Ms Hanson was shown saying she had “a lot of questions” about Port Arthur.

“An MP said it would actually take a massacre in Tasmania to change the gun laws in Australia,” she told Mr Muller.

“Haven’t you heard that? Have a look at it. It was said on the floor of parliament.”
